Solar Power
Does any one have any knowledge or experience with Solar Panels, I am thinking of a 2.2Kw or 3Kw to off set my energy bills.

Hi Phil,
In a couple of weeks we will be having a 3kw system installed for $7700. Our power bill in Perth is $1400 per year for 6000 kw, and the panels will provide about 6300kw in a year.
I worked out that spending $7700 for free electricity works out at about a 20% return on investment, and it's tax free!
True Value Solar are doing a lot of advertising at the moment. If you deal with them read the contract very carefully.Last edited by beer is good; 14th March 2011 at 02:28 PM. Reason: spelling

Hi Phil,
I've just signed up for a 2.2 kwh system from Solargain. I can't go larger as I don't have the available roof area. This system wont come close to suppying what we use, but our aim is to mitigate future power cost increases.
I have been reading up on this for several months, and believe that by properly managing our usage during the daylight hours, that the 2,2 kwh sytem will be able to produce grid feedin. In other words, if I minimise my usage during these hours that the solar can produce more than I use.
Since the feedin tariff (in vic) is $0.68 versus my cost of $0.175, every kwh that I can feedin to the grid is worth 3.88 kwh of purchased power. So in peak periods of sunshine, the system may actually give me a net cost approaching zero. Of course in winter, the system doesn't produce as much.
Overall, and averaged across the year, I think the system will have a sgnificant effect on my power bills.Chris

Thanks guys, it will be either a 3Kw or 2.2Kw unit depends on final costs, I use about 18Kwhrs per day and I have been told that a 3Kw unit should cover that with some spare and I will be able to use the credits to off set my gas bill, the 2.2Kw unit I reckon I will just about break even. What I have to consider is there is an approximate difference of $2500 to $3000 between 3Kw and 2.5Kw have to wait until all the quotes come in and the cost benefit has been done.

I've signed up for a 2.2kw system with InspireSolar for $6,000. It should generate enough of electricity for my family of 4.

Hi all.
I'm having a 3 kw system installed on wednesday. The cost to me in NSW is $11000.00 fully installed, that's after the government subsidies are deducted.
The feed in tarrif is $0.20 per kw unit.
It was $0.68 but the broke NSW govt. dropped it several months ago.
According to the December bill I am paying $0.22.122 per unit & my use is 16.35
units per day.
According to the installer it should cover the cost of all my power.
From the information I have i will be able to connect the inverter to my computer and monitor it's performance from the office.
Keith.

I am in Melbourne and have had a 2.16 kw system since May last year. My quarterly bills were around $350 ish, Winter,Summer slightly different.
Over Summer I will be ahead last bill, was $45 in credit, about to get a new one, will probably be the same or better I would imagine. During Winter I think it will cost money but will be a bit offset from Summer..
Hope this helps a little...

Thanks FT,
It's a bit of a relief to find out that my figuring could be about right.
Time will tell, but I'm feeling a lot better now.Chris

Just a thought Phil,
It's getting to the point, that if you are serious about solar you are going to have to move fairly quickly. Your system has to be fully installed, and all paperwork in, before 30th of June otherwise you will not get the rebate. I am guesing that lead times will start to stretch, as people try to get in before the end of rebates.Chris
